<h2>Remarks</h2>
<p>If the UMDF object tracking option (<b>TrackObjects</b>) has been enabled in WDF Verifier, you can use <b>!wudfext.wudfdumpobjects</b> to see any leaked objects that remain after the driver unloads. </p>
<p>If the <b>TrackObjects</b> option has been enabled, the address of the object tracker is automatically displayed when a leak is detected.  Use this address as <i>ObjTrackerAddress</i> when executing <b>!wudfext.wudfdumpobjects</b>. </p>
<p>This extension can be used at any time, even if UMDF has not broken in to the debugger. </p>
<p>If UMDF is version 1.9 or above, you can use either <a href="#Bookmark2794"><b>!wudfext.umdevstack</b></a> or <a href="#Bookmark2795"><b>!wudfext.umdevstacks</b></a> to determine the address of the object tracker. This address can then be passed to <b>!wudfext.wudfdumpobjects</b>.  Here is an example:</p>
